I will say this, I do not see any practical advantage to the Sony F65 vs. the Red Epic. Think about that: Sony's latest and great "4K" camera competes head to head with RED's latest, shipping "4K" camera and it's a wash. That's just huge. That's why I've had $5K sittings in RED's bank account for coming up on a year now, and am willing today (please call, RED!) to spend the $58K to have an Epic-M shipped my way. The Epic lives up to its name.
